Slide Rails

„

NOTE: The skid frame must be removed for this

procedure (see Removing Skid Frame in this sub-
section).

REMOVING

„

NOTE: When it is necessary to replace one or

both slide rails, it is recommended that one slide
rail be removed at a time. The remaining slide rail
will then hold the crossbraces, axles, and brackets
in their correct assembly order. Always mark the
mounting hole locations during disassembly to
speed up the assembly process and to prevent any
damage. This method is much quicker than to
completely disassemble the entire skid frame. To
replace either rail, use the following procedure.

1. Remove the end cap from the slide rail. Account

for a cap screw, lock nut, and two flat washers.

2. Remove the machine screw and lock nut securing

the wear strip to the front of the slide rail.

AG509D

3. Using a pipe wrench and starting from either end,

hook the edge of the wear strip with the pipe
wrench jaw and twist the wear strip off the slide
rail. Move the pipe wrench 7.5 cm (3 in.) and
again twist the wear strip off the rail. Repeat this
procedure until the wear strip is free of the rail.

„

NOTE: The wear strip can also be driven off the

slide rail; however, it is quicker to use the pipe
wrench.

4. Remove the cap screws securing the crossbraces to

the slide rail.
